Abstract

A hopper car unloading mechanism, comprising a drive mounted on the car frame, a longitudinal shaft, at each end of which a two-arm lever is rigidly mounted, kinematically connected to the unloading manhole covers using rods with the possibility of changing their length. The longitudinal shaft is mounted with the ability to move across the carriage, while the mechanism is adjusted by changing the length of one of the rods connected to the two-arm lever. The adjustable rod is made in the form of a hinged bolt pivotally connected to a lever and in contact with a threaded nut pivotally connected to the cover. The mobility of the shaft in the transverse plane is provided by connecting it directly or directly to the frame through the bracket in the form of a pendulum suspension.

Description

The utility model relates to the field of railway transport and can be used in lever-type devices for opening and closing the covers of unloading hatches of hopper cars.

The known mechanism of unloading a hopper car (patent RU 158555, 01/10/2016).

The device contains a drive shaft mounted on the frame of the car and kinematically connected with the covers of the discharge hatches, a manual drive for turning the longitudinal shaft is connected to the longitudinal shaft by means of a drive lever. Two shoulders levers are rigidly planted on the longitudinal shaft, between which the rods, made in the form of turnbuckles, are pivotally mounted.

The use in the known device of four adjustable rods, made in the form of lanyards, increases the complexity of their manufacture and maintenance costs.

The technical problem to which the proposed utility model is aimed is to reduce the complexity of manufacturing the mechanism and the cost of its maintenance.

The technical result is achieved by the fact that the hopper car unloading mechanism, comprising a drive mounted on the car frame, a longitudinal shaft, at each end of which two-arm levers are rigidly set, kinematically connected to the unloading manhole covers using rods. The longitudinal shaft is mounted with the possibility of moving across the carriage, while at each end of the longitudinal shaft one of the rods connected to the two-arm lever is made with the possibility of adjustment, by changing the length of which the unloading mechanism is adjusted. The adjustable rod is made in the form of a hinged bolt pivotally connected to a two-arm lever and in contact with a threaded nut pivotally connected to the cover. The mobility of the shaft across the car is ensured by connecting it directly or directly to the frame through the bracket in the form of a pendulum suspension.

The proposed utility model is presented in the drawings, where shown in FIG. 1 - the mechanism of unloading the hopper car in the position of the covers “closed”, the main view;

in FIG. 2 - mechanism for unloading the hopper car in the open position;

in FIG. 3 is a section AA in FIG. one;

in FIG. 4 - remote element B in FIG. one.

The unloading mechanism comprises a drive including a steering wheel 1 and a drive shaft 2, a longitudinal shaft 3, a drive lever 4, a two-arm lever 5, a rod 6 and an adjustable rod 7, covers 8.

The longitudinal shaft 3 with the help of the drive lever 4 transfers the force from the drive shaft 2, on which the two-arm lever 5 is rigidly mounted, to the rod 6 and the adjustable rod 7.

The longitudinal shaft 3 is mounted on the frame using the bracket 9 in the form of a pendulum suspension, ensuring its movement across the car.

The bracket 9 is pivotally mounted on the frame using the brackets 10.

Moving the longitudinal shaft 3 across the car allows the use of an adjustable traction 7, by changing the length of which the unloading mechanism is adjusted only on one side of the two shoulders of the lever 5.

Changing the length of the adjustable rod 7 is provided using the hinge bolt 11, pivotally connected to a two-arm lever and in contact with a threaded nut 12, pivotally connected to the cover.

The implementation of the mechanism of unloading the hopper car of a smaller number of adjustable rods reduces the complexity of manufacturing the mechanism, the cost of its maintenance.

Claims (3)
